ABSTRACT:
An improved method for carrying out an extrusion is provided, wherein an extrusion material in a flowable state is passed through a die under a pressure to impart a desired shape thereto, and the extrusion is carried out while the die is resonated by an ultrasonic wave in such a manner that the resonance occurs at an n wavelength, wherein n is m/2 and m is a positive integer. Further, an apparatus suitable for carrying out this extrusion method is provided.
